SPECIFICATION forming part of Letters Patent No. 647,520, dated April17, 1900.

Application filed May 2, 1899. Serial No. 715,331, (No model.)

To aZZ whom it nuty concern:

Beit known thatI, HIRAM Asrrnn PRINDLE, a citizen of the United States,residing at New Milford, in the county of Portage and State of Ohio,have invented certain new and useful Improvements in Pattern-Holders;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which .it appertains to make and use the same.

The invention has relation to pattern-holders, and more particularly toa device for holding patterns used in the cutting of fabric for patchesforquilts, cushions, chairs, robes, or, in fact, any article capable ofbeing cut with shears around a stiff pattern.

The object of the invention is to provide a device of this charactereasy to use and which shall be simple of construction, durable in use,comparatively inexpensive of production, and by means of which theoperation'of cutting patches will be greatly facilitated.

With this object in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed and claimed.

In the drawings, Figure l is a perspective view of the improvedpattern-holder, showing the pattern secured to the heads and a foldedpiece of fabric clamped between the patterns and ready to be cut tocorrespond to the outline thereof. Fig. 2 is a detail perspective Viewof one of the pattern-heads, showing the pattern secured thereto. Fig. 3is a similar view of the other pattern-head with its pattern securedthereto. Fig. 4 is a vertical sectional view through the twopattern-heads, showing the guide-pins of one head projecting into theguide sockets orapertures of the other head. Fig. 5 is a side elevationof the rear portion of the frame, one of the standards being broken awayto more clearly illustrate the construction of the actuating-spring.

In the drawings, 1 and 2 denote two jaws, the former being provided atits rear end with standards 3, between the upper ends of which the jaw 2is pivoted.

4 denotes a clamp, by means of which the device is secured to a shelf,table, or other object. The lower jaw l is pivoted between ears 6 of theclamp and is held in the desired adjustment by a thumb screw and bolt 7.

8 denotes a spring secured to the rear end of the jaw 1 and having anarm that projects rearwardly. 9 denotes a link which connects therearwardly-projecting arm of this spring with the rearwardly-projectingend of the jaw 2. The energy of the spring is exerted when the jaw 2 iselevated to hold said jaw in its elevated position, and when depressedits energy is exerted to hold the jaw in its depressed position.

10 and 11 denote, respectively, the upper and lower pattern-heads, thestems 11' of which are swiveled to turn' laterally in the free forwardends of the jaws. One of the heads, preferably the head 10, is free torock a slight distance in the direction of the length of the jaw, thebearing in said jaw for the shank of the head being slightly elongated,as shown in Fig. 4.

12 denotes the patterns, which are secured to said heads by a screw 13and a clamp-plate 14:. One of the pattern-headsfor instance, the upperone 10-is provided with apertures or sockets 15, and the pattern andclampingplate are provided with similar apertures 16, which registerwith the apertures 15. The pattern,which is secured to the lower head11, is provided with corresponding apertures 17, through which projectpins 18, extending'upwardly from said head. These pins 18 are adapted toenter the apertures 0f the upper patternfits holding-plate,and theupperhead, and when they engage these apertures the edges of the twopatterns are parallel and are retained parallel in the rotation of thehead.

In operation, the goods from which the pieces are to be out are foldedand placed upon the lower pattern, the pins being made to pass throughthe fabric. lowered until its plate contacts with the points of thepins. Now by turning one of the-pattern-heads and slightly rocking thehead 10 the pins are caused to find the aper-- tures in the oppositehead, and when they do it is evident that the edges of the two patternshave been perfectly aligned, and the op erator may now proceed to trimolt the edges of the goods around the edges of the pattern.

It will of course be understood that various The upper jaw is nowchanges in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is

1. In a pattern-holder, the combination with the clamping-jaws; ofpattern-heads swiveled theretoto rotate with respect to the same, andprovided with coacting pins and apertures, substantially as and for thepurpose set forth.

2. In a pattern-holder, the combination with the clamping-jaws,pattern-heads swiveled thereto and provided with ooacting pins andapertures; of patterns secured to said heads and provided with apertureswhich register with the aforesaid apertures, substantially as and forthe purpose set forth. 3. In a pattern-holder, the combination with theclamping-jaws; of pattern-heads, one head having a swiveled non-rockingcon nection with one jaw, and the other head having a swiveled androcking connection with the other jaw, said heads being provided withcoacting pins and apertures, substantially as and for the purpose setforth.

4. In a pattern-holder, the combination with the clamping-jaws providedwith apertures one of which flares; of pattern-heads the stems of whichare swiveled in said apertures, one of said stems having a rockingmovement in said flaring aperture independent of its swiveled movement,and said heads being provided with coacting pins and apertures,substantially as and for the purpose set forth.

5. In a pattern-holder, the combination with pivotally-supported jawspivoted together; of a spring connected to the rear end of one of saidjaws and provided with a rear- Wardly-extending arm, a link pivoted tothe rear end of the other jaw and to the end of said arm, whereby theaction of the spring is exerted to hold the forward ends of said jaws ineither an open or closed position, and coacting pattern-heads carried bytheforward ends of said jaws, substantially as and for the purpose setforth.

6. In a pattern -holder, the combination with the clamp adapted to besecured to a table, bench, or like support; of jaws piv otally connectedat their rear ends, one of said jaws being adjustably pivoted to saidclamp to swing up and down, a spring connected to the rear end of one ofsaid jaws and provided with arearwardly-extending arm, a link pivoted tothe rear end of the other jaw and to the end of the said arm, wherebythe action of the spring is exerted to hold the forward ends of saidjaws in either an open or closed position, and coaoting pattern-headscarried by the forward ends of said jaws, substantially as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

HIRAM ASHER IRINDLE.
